What is the frequency response of the Butterworth high pass filter?
Butterworth stated that: "An ideal electrical filter should not only completely reject the unwanted frequencies but should also have uniform sensitivity for the wanted frequencies". = 1, the amplitude response of this type of filter in the passband is 1/√2 ≈ 0.7071, which is half power or −3 dB.
What is the range of the Butterworth filter?
Lowpass Butterworth Filter
For data sampled at 1000 Hz, design a lowpass filter with no more than 3 dB of ripple in a passband from 0 to 40 Hz, and at least 60 dB of attenuation in the stopband.
What is the limitation of Butterworth filter?
Butterworth filters do not always provide a good approximation of the ideal filter response because of the slow roll-off between the passband and the stopband.
Third-order Butterworth Low Pass Filter
and finally our circuit of the third-order low pass Butterworth Filter with a cut-off corner frequency of 284 rads/s or 45.
2) Hz, a maximum pass band gain of 0.5dB and a minimum stop band gain of 20dB is constructed as follows.

Highpass Butterworth Filter Specify a cutoff frequency of 300 Hz, which, for data sampled at 1000 Hz, corresponds to 0 . 6 π rad/sample.
